You should always give your seat on the subway to the old guy — not just because it's the right thing to do, but because that old guy might be a retired Sith lord with a penchant for skewering snot-nosed kids with poor transit etiquette.

Sean Soong directed SubWars, his animated tribute to Star Wars, Naruto, and gory action films. When no one on the train will give up their seat to an old man, he takes his bloody revenge. Only one of Naruto's Akatsuki is willing to put a stop to his lightsaber mayhem.
